[simple-oauth2] Allow http options for getToken (#39940)

* [simple-oauth2] Allow http options for getToken

According to the docs of simple-oauth2 the getToken function optionally accepts an httpOptions object:
https://www.npmjs.com/package/simple-oauth2#authorization-code-flow

```
// Optional per-call http options
const httpOptions = {};
 
// Save the access token
try {
  const result = await oauth2.authorizationCode.getToken(tokenConfig, httpOptions);
  const accessToken = oauth2.accessToken.create(result);
} catch (error) {
  console.log('Access Token Error', error.message);
}
```

* [simple-oauth2] Allow scope in getToken config

According to the docs of simple-oauth2 a scope property is allowed:
https://www.npmjs.com/package/simple-oauth2#authorization-code-flow

```
// Get the access token object (the authorization code is given from the previous step).
const tokenConfig = {
  code: '<code>',
  redirect_uri: 'http://localhost:3000/callback',
  scope: '<scope>', // also can be an array of multiple scopes, ex. ['<scope1>, '<scope2>', '...']
};
 
// Optional per-call http options
const httpOptions = {};
 
// Save the access token
try {
  const result = await oauth2.authorizationCode.getToken(tokenConfig, httpOptions);
  const accessToken = oauth2.accessToken.create(result);
} catch (error) {
  console.log('Access Token Error', error.message);
}
```

* [simple-oauth2] Fix missing type for scope

* [simple-oauth2] Add http options to all func

* [simple-oauth2] Update interface for WreckHttpOptions

* [simple-oauth2] bump version to trigger rebuild

* [simple-oauth2] Fix build errors
